This technology allows us to use blades with shrouds. But design engineers are faced with the problem of blade placement because of the disk size and root dimensions.The problem of increasing life and cyclic durability, vibration strength, and lightweight design of the turbine gas turbine wheels, can be solved by an elimination of blade - disk locks.The technology of manufacturing one-piece blisks by connecting the blades with the disc part using hot isostatic pressing was developed. Increasing an engine life and efficiency as well as mass reduction can also be achieved by increasing blade numbers and decreasing disk diameter. A nacelle provides an outer flow duct for the thrust fan blades and a secondary flow duct carries flow from the integral secondary flow blades as cooling air for components of the reverse flow turbine engine.īimetallic Blisks with Shrouded Turbine Blades for Gas Turbine Enginesĭirectory of Open Access Journals (Sweden)įull Text Available The paper discusses prospects of using blisks with shrouded blades. The fan blisk incorporates a set of thrust fan blades extending from an outer hub and a set of integral secondary flow blades extending intermediate an inner hub and the outer hub. ![]() Secondary air flow is provided for a ducted fan having a reverse flow turbine engine core driving a fan blisk. ![]() ![]() Reverse Flow Engine Core Having a Ducted Fan with Integrated Secondary Flow Blades ![]()
